Let's get this queued up for testing, thanks John.

Cheers, appreciated

@Kashyap, You mentioned that when testing you saw a performance regression from v5.11 -> v5.12 - any idea on that yet? Can you describe the scenario, like IO scheduler and how many disks and the type? Does disabling host_tagset_enable restore performance?

From checking differences between those kernels, I don't see anything directly relevant in sbitmap support or in the megaraid sas driver.

Thanks,
John
